Setting up CommonQt on OSX

CommonQt can be tricky to setup due to its dependencies from C++ land. Tricky enough to warrant writing down the steps I went through to get it running on Mac OS 10.7:

1. If you don't already have Xcode, install it because you'll need g++.

2. Grab and install the Qt Libraries (not the Qt SDK). I used version 4.7.4.

3. Install CMake. (I used brew install cmake.)

4. Download, compile and install the SMOKE library:

   $ git clone git://anongit.kde.org/smokegen
   $ cd smokegen
   $ cmake .
   $ make install
   
   $ cd ..
   $ git clone git://anongit.kde.org/smokeqt
   $ cd smokeqt
   $ cmake -DSmoke_DIR="$PWD/../smokegen/cmake" .
   $ make install
   

   At this point, smokephonon failed to build so I had to manually install the two modules I actually needed:

   $ make -C qtcore install
   $ make -C qtgui install
   

5. Get an SBCL with threads enabled and Quicklisp.

6. CommonQt needed a couple of tweaks for OSX and recent changes in SMOKE. While said changes aren't reviewed and integrated into the main repository, you can fetch them as follows:

   $ cd ~/quicklisp/local-projects
   $ git clone git://gitorious.org/~luismbo/commonqt/commonqt-luis.git
   $ cd commonqt-luis
   $ git checkout modular-smoke-and-osx-fixes
   

7. Start SBCL and (ql:quickload :qt).

Hopefully that went well. Next we'll try and run an application.

1. Enable the swank-listener-hooks contrib by adding (slime-require 'swank-listener-hooks) to your SLIME configuration.
2. (asdf:load-system :qt-tutorial)
3. (asdf:load-system :qt-repl)
4. (qt-repl:start-gui-thread)
5. And finally, (qt-tutorial-14::test)!

If not running under SLIME, (asdf:load-system :qt-tutorial) followed by (qt-tutorial-14:main) would be sufficient.

If you want to try and skip the C++ compilation steps, grab this tarball with libcommonqt.dylib and libsmoke*.dylib. You should place libcommonqt.dylib in CommonQt's source directory. The SMOKE libs go into /usr/local/lib or similar.
